The CHS is administratively part of Fisheries and Oceans Canada's Oceans and Ecosystems Science Sector. According to mandated obligations of the Oceans Act and the Canada Shipping Act, the CHS is led by the Hydrographer General of Canada who is responsible for gathering, managing, transforming and disseminating bathymetric, hydrographic and nautical data and information into paper and ...
Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
According to historian Raymond Douville, this point is the origin of the name Grondines, probably given by the boaters who had to go around, at the rising tide, the many pebbles that the waves hit in dull roars and whose echoes resonated on the escarpments of the coast.

On nautical charts, the top of the chart is always true north, rather than magnetic north, towards which a compass points. Most charts include a compass rose depicting the variation between magnetic and true north. However, the use of the Mercator projection has drawbacks. This projection shows the lines of longitude as parallel.
Skookumchuck Narrows [1] is a strait forming the entrance of Sechelt Inlet on British Columbia's Sunshine Coast in Canada. Before broadening into Sechelt Inlet, all of its tidal flow together with that of Salmon Inlet and Narrows Inlet must pass through Sechelt Rapids. At peak flows, standing waves, whitecaps, and whirlpools form at the rapids ...
A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).
